And one thing we ve been noticing is the frequent use of a new exterior sheathing product called zip system.
How to attach siding to zip sheathing.
Let s take a look at overdriven fasteners and their effect on zip system sheathing.
Zip system roof and wall sheathing panels are oriented strand board osb structural panels with built in protective overlays that eliminate the need for building wrap or roofing felt.
Zip system is easily identified by its green colored panels that are attached and sealed with black zip tape on all the exterior seams of the home.
This type of sheathing does not add significantly to a wall s strength but can greatly increase its insulation value.
Zip system sheathing is a type of osb.
The definition of an overdriven fastener.
Once the sheathing seams have been taped with zip system tape the sheathing functions as a water resistive barrier wrb as well as an air barrier.
In this tutorial you will learn.
Cladding weight shall include all materials supported by the fasteners on the exterior side of the foam sheathing e g.
Rigid foam and cellulose fiber panels may be attached directly to wall studs or masonry walls under or over structural sheathing depending upon nailing requirements or in some cases over existing siding before re siding.
In such cases both the cladding and the wsp sheathing weight must be included in the calculation for the cladding weight.
It s basically the same 7 16 inch osb wall sheathing bonded to either a 1 2 inch r 3 6 or 1 inch r 6 6 polyiso foam panel.
Wood structural panel sheathing may be installed between the cladding material and the foam sheathing.
Nails or other code recognized fasteners used to attach zip system sheathing to supporting framing members may occasionally penetrate beyond the face of the zip system panels.
Rigorously engineered to streamline continuous air and water barrier performance in structural roof and wall assemblies it has changed the way teams build.
